Cal-Mag Citrate - 8 oz.
 
NOW Calcium & Magnesium Citrate Powder with Vitamin D Powder is an optimal bone structure support formula designed by NOW's certified nutritionists. It contains key nutrients that play essential roles in bone metabolism.   The citrate forms of calcium and magnesium are highly absorbable and support not only strong bones and teeth but muscle and nerve function as well. Vitamin D is included for its synergism with calcium and magnesium and its role in the maintenance of mineral homeostasis and bone structure.

Calcium is the chief supportive element in bones and teeth. Calcium salts make up about 70 percent of bone by weight and give your bone its strength and rigidity.

Almost all of the calcium in the human body is held in the bones and teeth. The remaining 1 percent of calcium circulates in the bloodstream, where it performs a variety of important functions. It helps to contract muscles and helps regulate the contractions of the heart. It plays a role in the transmission of nerve impulses and in blood clotting.

Calcium is involved in the stimulation of contractions of the uterus during childbirth and in milk production. It also regulates the secretion of various hormones and aids in the functioning of various enzymes within the body. Since vitamin C is important for so many necessary bodily functions, taking a liquid mulitvitamin that is rich in vitamin C is advised.

When we take Calcium, it absorbed in the small intestine and passes from there either into the bloodstream or ultimately into the bones. The most efficient absorption of calcium is dependent on the presence of vitamin D in the body, which is a key ingredient in the various hormones that enable calcium to pass from the digestive system into the blood or bones.

Similarly, there are optimal ratios of phosphorus to the amount of calcium consumed that permit calcium to be more completely utilized. Hormonal secretions of the parathyroid and thyroid glands (parathyroid hormone and calcitonin, respectively) also help maintain calcium equilibrium in the blood.

These regulatory mechanisms help to prevent a deficiency in calcium from developing in the bloodstream. When such a deficiency does develop, parathyroid hormone acts to transfer calcium from the bones in order to maintain the mineral's all-important presence in the bloodstream. This of course strips your bones of their calcium and in turn weakens your bones, making them more brittle and subject to breaking.

Magnesium is a mineral that is critical for energy production and metabolism, muscle contraction, nerve impulse transmission, and bone mineralization.  It is a required cofactor for an estimated 300 enzymes.  Among the reactions catalyzed by these enzymes are fatty acid synthesis, protein synthesis, and glucose metabolism.  Magnesium status is also important for regulation of calcium balance through its effects on the parathyroid gland.  NOW Magnesium Citrate Powder is a highly bioavailable form of Magnesium and contains no excipients or fillers.
